# Overlays
|
||
|
|
|
||
|
|
Two directories under `iso-profiles/antergos/` control what goes into the ISO.
|
||
|
|
|
||
|
|
```
|
||
|
|
iso-profiles/antergos/
|
||
|
|
├── profile.yaml
|
||
|
|
├── root-overlay/ # → rootfs (squashfs)
|
||
|
|
└── live-overlay/ # → live environment (initramfs)
|
||
|
|
```
|
||
|
|
|
||
|
|
## How overlays work
|
||
|
|
|
||
|
|
- `root-overlay/` files are merged into the root squashfs — they become part of the installed system
|
||
|
|
- `live-overlay/` files are copied into the live environment only — they're not present after installation
|
||
|
|
- Overlays are **self-contained** (no symlinks to external directories) so the repo builds standalone
|
||
|
|
- Live-overlay files are **copied** via `cp -LR` in `make_livefs()`, not overlay-mounted. Deleting a file from live-overlay exposes the package version underneath
|
||
|
|
|
||
|
|
> **Disclaimer:** No symlinks were harmed in the making of this ISO. Well, maybe a few. We killed some.
|
||
|
|
|
||
|
|
> Also: this ISO is 100% systemd-free. Not even a trace. We checked. Twice.
